The nextnano.QCL software for Quantum Cascade Lasers

This website describes the nextnano.QCL software,
a NEGF quantum transport code written by Thomas Grange.
The nextnano.QCL software has been developed to simulate electron dynamics in heterostructures like superlattices and quantum cascade lasers (QCLs). It can also be used to simulate absorption spectra in quantum wells (QWs) and transport in resonant tunneling diodes (RTDs).
